Simmerrings | Simmerring BAUM.../SLto DIN 3760 A/AS Simmerring BAUM.../SL Simmerring BAUMX7, BAUMSLX7, BAUM, BAUMSL Simmerring BAUM ... Simmerring BAUMSL ... Product description Standard types according to DIN 3760 with outer elastomer sleeve and spring-loaded fluorine rubber sealing lip for high thermal and chemical requirements. Available with or without additional dust lip to protect against light to medium levels of exterior soiling. Product properties ■ Outer casing: elastomer (smooth, grooved = X7) ■ Additional dust lip (BAUMSL, BAUMSLX7] ■ Friction-optimised sealing lip profile ■ Axles (when subject to moderate dirt) ■ Agricultural and construction machinery transmissions Product advantages ■ Broad range of possible applications in every sector of ■ Increased thermal stability and chemical resistance ■ Reliable sealing of the housing bore, even with increased roughness of the bore, thermal expansion and split housings, thus a sealing of low viscosity and gaseous media also ■ Advantages when sealing low viscosity and gaseous media ■ Additional dust lip as additional seal against moderate and medium dust and dirt ingress from outside (BAUMSLX7). (Note: can lead to temperature increase from frictional heat) © Freudenberg Simrit GmbH & Co. KG | Simmerrings and Rotary Seals eCatalog 2009 1
